I don't think I'll ever see paths in the core modules (which I don't
mind) since lua tries to be transparent to them and wouldn't know how
to strip the filename out of a filepath in a portable way. But an
opaque filepath as it was given to loadfile() when the module was
require()'d seems reasonable. Since it uses user-supplied information
to find the file, it might as well tell us back which path worked.
